When the PDF Translator seems to misbehave, the cause is usually one of two things: something stopped the tool from running, or it ran but the result is not usable. This guide starts with the fastest checks, then walks through the common problems and exact fixes.
Quick Checks First
- Refresh the page - a stalled session is the most common cause of nothing happening.
- Confirm the input is not empty and actually contains what you meant to submit.
- Try the smallest possible input; if that works, the issue is size, not the tool.
- Turn off browser extensions that block scripts, then reload and test again.
- Update or switch browsers if the problem repeats across sessions.
Common Problems and How to Fix Them
The translation is nonsensical
The document may be scanned or layout-confused - OCR first, then translate cleaner text.
Technical terms are wrong
Domain vocabulary needs human review - treat output as a draft, not a deliverable.
Layout collapsed in translation
Translation changes line lengths and flow - expect reflow; formatting is a separate pass.
Nothing extracted to translate
No text layer exists - run OCR on scans before translating.
The tone feels wrong for legal use
Machine translation lacks legal nuance - engage a certified translator for binding documents.
Mixed languages confused it
Multilingual documents translate unpredictably - separate languages where possible.
When It Works but the Output Is Poor
If the tool runs fine but the result misses, the problem is almost always the brief, not the software:
- Treating machine translation as contract-grade
- Translating scans without OCR first
- Ignoring formatting and technical terms
- Publishing output without human review
How to Stop It Happening Next Time
- Keep a saved prompt template for every task you repeat.
- Change one setting per generation so causes stay obvious.
- Run a two-minute sanity test with known input after any update.
- Note every failure and its fix; a short troubleshooting log pays for itself.
Still Stuck?
Reproduce the problem with the smallest possible input and note the exact steps that triggered it. A one-line description of what you did, what you expected and what happened is enough to get a precise answer from support or a colleague.
Frequently Asked Questions
How accurate is the translation?
Useful for understanding content, not for certified use. Always review output before relying on it.
Does it keep the document layout?
Structure is broadly preserved, but translated text reflows - expect formatting differences.
Can it handle scanned documents?
After OCR creates a text layer - scans contain images of text, not text itself.
Are my files uploaded?
No - processing happens entirely in your browser.
